Description

When creating a git diff with rbt diff, the -M option is automatically
used if available and the user has no way of making rbt pass in
--no-renames to git diff.

This change adds a --no-renames flag to the rbt diff command which then
gets passed into git diff.

Testing Done

Tests were run.

Instead of checking the tool type, we should add a flag to SCMTool like supports_no_renames (defaulting to False) and set supports_no_renames = True in clients/git.py. Then we can check:

if self.options.no_renames:
    if tool.supports_no_renames:
        # ...
    else:
        logging.error('The %s SCM tool does not support diffs without renames',
                      tool.type)

I'm not sure that we should be using extra_args for this. This seems like a job for a keyword argument.

Change Summary:

Update to use keyword arg for no_renames and address review comments.

Teeny tiny nitpicks :) You should probably get either David and/or Christian's feedback about this since we're adding new arguments to diff() and that could break third party SCM clients.

I'm happy with this as-is. Will wait for feedback from Chirstian and/or David before landing, however.
